Php 使用数字、数字字母、字母数字和字母组合对数组进行排序

我正在尝试排序和数组，但是，无法获得预期的数组

我有这样一个数组：

Array
(
    [0] => 5
    [1] => 7
    [2] => 8
    [3] => 9
    [4] => 10
    [5] => 11
    [6] => 12
    [7] => 13
    [8] => 14
    [9] => 15
    [10] => 16
    [11] => 17
    [12] => 18
    [13] => 19
    [14] => 20
    [15] => 21
    [16] => 23
    [17] => 24
    [18] => 26
    [19] => 28
    [20] => 29
    [21] => 30
    [22] => 31
    [23] => 32
    [24] => 33
    [25] => 34
    [26] => 35
    [27] => 36
    [28] => 37
    [29] => 38
    [30] => 39
    [31] => 40
    [32] => 41
    [33] => 42
    [34] => 44
    [35] => 46
    [36] => 48
    [37] => 50
    [38] => 52
    [39] => 54
    [40] => A
    [41] => B
    [42] => 3
    [43] => 4
    [44] => 6
    [45] => A1
    [46] => B1
    [47] => 1A
    [48] => 22
    [49] => 25
    [50] => 27
    [51] => 1B
)

当我运行asort（$arr）时，它返回：

Array
(
    [47] => 1A
    [51] => 1B
    [42] => 3
    [43] => 4
    [0] => 5
    [44] => 6
    [1] => 7
    [2] => 8
    [3] => 9
    [4] => 10
    [5] => 11
    [6] => 12
    [7] => 13
    [8] => 14
    [9] => 15
    [10] => 16
    [11] => 17
    [12] => 18
    [13] => 19
    [14] => 20
    [15] => 21
    [48] => 22
    [16] => 23
    [17] => 24
    [49] => 25
    [18] => 26
    [50] => 27
    [19] => 28
    [20] => 29
    [21] => 30
    [22] => 31
    [23] => 32
    [24] => 33
    [25] => 34
    [26] => 35
    [27] => 36
    [28] => 37
    [29] => 38
    [30] => 39
    [31] => 40
    [32] => 41
    [33] => 42
    [34] => 44
    [35] => 46
    [36] => 48
    [37] => 50
    [38] => 52
    [39] => 54
    [40] => A
    [45] => A1
    [41] => B
    [46] => B1
)

它是排序正常，但是，我愿意让它排序根据组合，如数字，数字字母，字母，字母

例如，此数组应如下所示：

Array
(
    [42] => 3
    [43] => 4
    [0] => 5
    [44] => 6
    [1] => 7
    [2] => 8
    [3] => 9
    [4] => 10
    [5] => 11
    [6] => 12
    [7] => 13
    [8] => 14
    [9] => 15
    [10] => 16
    [11] => 17
    [12] => 18
    [13] => 19
    [14] => 20
    [15] => 21
    [48] => 22
    [16] => 23
    [17] => 24
    [49] => 25
    [18] => 26
    [50] => 27
    [19] => 28
    [20] => 29
    [21] => 30
    [22] => 31
    [23] => 32
    [24] => 33
    [25] => 34
    [26] => 35
    [27] => 36
    [28] => 37
    [29] => 38
    [30] => 39
    [31] => 40
    [32] => 41
    [33] => 42
    [34] => 44
    [35] => 46
    [36] => 48
    [37] => 50
    [38] => 52
    [39] => 54
    [47] => 1A
    [51] => 1B
    [45] => A1
    [46] => B1
    [40] => A
    [41] => B
)

您可以将用户定义的排序与

uasort

一起使用，请检查

---

您使用过哪些PHP函数。。。请尝试

natsort（）

？@PaulT。我使用了

asort（）

。我也测试了

natsort

，但是，在我的案例中，它返回与asort相同的输出，即比较数字与字符串。数组中的所有数字都像27，27是Int还是String？当A1大于1A时，您的定义是什么？所有这些都取决于您的业务逻辑。您可以使用uasort来定制您的Sort。您可以提供给我您的php数组的某个位置来获取它并执行一些测试代码吗？它看起来似乎正在工作，但是，您可以解释一下，

$a

和

$b

变量指的是什么。@AayushDahal它是的参数

uasort($array,function($a,$b){
    if(is_numeric($a) && is_numeric($b)){
        return $a - $b;
    }elseif(is_numeric($a)){
        return -1;
    }elseif(is_numeric($b)){
        return 1;
    }else{
        $length = max(strlen($a),strlen($b));
        return strcmp(str_pad($a,$length,"z",STR_PAD_LEFT),str_pad($b,$length,"z",STR_PAD_LEFT));
    }
});
